I had a rear brake cylinder leak like a sieve. Stomped on the brakes
and hardly any braking force was available. Luckily, it wasn't far
from home and I wasn't going fast.
So I look and there's no fluid in the resevoir. I replace the rear
cylinders and bleed the systems. One system(diagonally) worked. I
then replace the master cylinder, bleed the system and all is fine.
My question though, is about the resevoir. I had to reuse it on the
new master cylinder, except I can't seat it all the way down as with
the original cylinder. I looked at the replacement master cylinder
and the rubber grommets that the resevoir fits into. The
grommets/bushings aren't as deep (over all length of grommet/bushing
is shorter between the nipples and flair) as the original. So now
there's a gap between the resevoir seat and the grommet/bushing
seats. The gap is about the amount that the grommet/bushing is
short. Does this sound like a problem? I have no leaks or seeps at
the interface and the brakes have felt good.
